What is Medi-Dart?

The MEDI-DART Projectile, Extension, or Crossbow syringe, invented by
a group of central Alberta ranchers, makes medicating pasture cattle easy
and less stressful for livestock. The patented MEDI-DART systems are easy
to use and inject larger doses of medication than other medicating systems.

MEDI-DART is used to give a single intramuscular or subcutaneous injection
to livestock without restraining the animal. MEDI-DART also self-ejects
once the injection is completed. At the end of the injection an ejector
loop is pushed ahead which removes the needle from the animal for easy
retrieval of the syringe.

Three variations are available; the
Crossbow MEDI-DART, which further increases accuracy, the Projectile
MEDI-DART which incorporates the basic principle of the bow and
arrow, and the Extension MEDI-DART, which simply uses the added
length of a pole.

With the Crossbow Projectile system, the syringe can hold 30cc
of medication and has a 30 foot range to medicate the animal. With
the Bow and Arrow Projectile system, the syringe on the end of the
arrow can hold up to 30cc of medication and the user has a 20 foot
range. The Extension MEDI-DART can hold up to 35cc of medication
and gives the user a 6 foot reach. The syringe is released from
the pole after the animal has been poked.

MEDI-DARTS use a simple bicycle pump to create air pressure which
injects the medication and upon completion of the injection pushes
the ejector loop ahead, forcing the needle out of the animal.
